FIELD OF THE INVENTION

This invention relates generally to electrophilic peptide analogs as inhibitors of trypsin-like serine proteases. These compounds are dipeptides in which an electrophilic derivative of an α-amino acid is conjugated with an N,N-disubstituted α-amino acid. The N,N-disubstituted α-amino acid conjugates of the electrophilic amino acid analog are derivatives of an amino acid where the α-amino group is alkylated and acylated or diacylated to give alicyclic or cyclic substituents. The electrophilic functional groups used to derivatize these peptide analogs are: boronic acids and their esters, α-mono- and α-perhaloketones, aldehydes, vicinal di- and tricarbonyl compounds, α-mono- and α,α-dihalo-β-ketoesters.

BACKGROUND OF THE INVENTION

Electrophilic tripeptide analogs containing the ((D-phenylalanyl)prolyl)-arginyl-sequence are well known as effective inhibitors of the trypsin-like serine protease thrombin. H-(D)Phe-Pro-ArgCH₂ Cl was first reported by Kettner and Shaw (Thromb. Res. 14, 969 (1979)) to be a selective but irreversible inhibitor of human thrombin. A number of studies looking for alternatives to the electrophilic P₁ argininechloromethylketones that would yield a reversible protease inhibitor have been reported. Bajuez et al. (Folia Haematol. 109, s. 16 (1982)) found the corresponding aldehyde, D-phenylalanyl-prolyl-arginal, to be a reversible thrombin inhibitor with a K_(i) =75 nM for human thrombin. The nitrile analog, D-phenylalanyl-prolyl-NHCH((CH₂)₃ NHC(═NH)NH₂)--CN, was found to be substantially less potent with a K_(i) =700 nM (Kaiser et al., Pharmazie 46, 128 (1991)). A retroamide inhibitor, with the D-phenylalanyl-prolyl-sequence and 2-(4-guanidinophenylalanyl)-N-acetyl-2,2-difluoroethylamine substituting for an electrophilic arginine derivative, is a good inhibitor with a K_(i) of 70 nM for thrombin (Altenburger and Schirlin, Tetrahedron Lett. 32, 7255 (1991)). Cheng et al. claim that the substitution of racemic diphenyl 1-amino-4-methoxybutylphosphonate for an electrophilic arginine derivative gives very good inhibitors with a K_(i) =4.8 nM (Tetrahedron Lett. 32, 7333 (1991)). Iwanowicz et al. (Bioorgan. Med. Chem. Lett. 2, 1607 (1992)) has studied the efficacy of (D-phenylalanine)prolyl-conjugated to --NHCH[(CH₂)₄ NH₂ ]CH(OH)CO₂ Me) and --NHCH[(CH₂)₄ NH₂ ]C(═O)CO₂ Me derivatives. The most effective inhibitor of human thrombin reported to date is the boropeptide acetyl-D-phenylalanyl-prolyl-boro arginine with a K_(i) =0.041 nM (Kettner et al., J. Biol. Chem. 265, 18289 (1990)).

Walker et al. (Biochem. J. 230, 645 (1985)) published a comparative study of irreversible thrombin inhibitors based on the D-pherlylalarlyl-prolyl-argininyl sequence confirming the earlier report by Kettner and Shaw (1979). H-(D)Phe-Pro-ArgCH₂ Cl was found to be the most effective inhibitor (K_(i) =25 nM) while replacing the D-phenylalanine with 4-amino-D-phenylalanine or ω-benzoyl-D-lysine gave less active analogs. Compounds in development include -(prolyl)arginal derivatives with a variety of unusual P₃ amino acids including D-N-methylphenylglycine, Boc-D-fluorophenylglycine as well as constrained cyclized derivatives of D-phenylglycine and D-phenylalanine (Shuman et. al., J. Med. Chem. 36, 314 (1993)). Balasubramanian et al. (J. Med. Chem. 36, 300 (1993)) has reported an extensive study of replacements for the P₃ D-phenylalanine of D-phenylalanyl-prolyl-arginal and found the dihydrocinnamoyl group to be effective, although somewhat less potent.

Patent disclosures in this area have centered around suitably protected peptides composed of natural and unnatural amino acids. In U.S. Pat. No. 5,187,157 DuPont Merck has disclosed peptides comprised of C-terminal boronic acid derivatives of lysine, ornithine and arginine as reversible inhibitors of trypsin-like serine proteases, as well as a series of boropeptides active as elastase inhibitors in U.S. Pat. No. 4,499,082. In European Patent Application EP 471 651 A2 Sandoz disclosed borolysine and boroarginine peptide analogs containing at least one unnatural hydrophobic α-amino acid substituted with groups such as the trimethylsilyl- or naphthyl-. In U.S. Pat. No. 5,106,948 was disclosed a series of boropeptides that are effective as cytotoxic agents. In PCT Application WO 92/07869, Thrombosis Research Institute has disclosed tripeptide analogs containing a P₂ proline and an unnatural disubstituted amino acid at P₃. A variety of electrophilic and non-electrophilic α-amino acid analogs were claimed as suitable P₁ substituents. Tripeptide antithrombotic agents limited to α-alkyl and α-aryl or heteroaryl substituted glycines at P₃ conjugated to -(prolyl)arginal were been disclosed by Lilly (European Patent Application EP 479 489 A2). Marion Merrell Dow disclosed a series of activated electrophilic ketone analogs of peptidase substrates useful for inhibiting serine-, carboxylic acid- and metallo-proteolytic enzymes; compounds are peptides composed of suitably protected α-amino acids conjugated to an electrophilic ketone derivative of an α-amino acid (European Patent Applications EP 417 721 A2, EP 364 344 A2, EP 363 284 A2, EP 195 212 A2). Astra has disclosed a series of α-((trifluoroethyl)oxymethyl)-arginine tripeptides (European Patent Application EP 0 530 167 A). Georgia Tech Research Corporation disclosed peptidyl ketoamides, -ketoacids and -ketoesters as inhibitors of serine and cysteine proteases (WO 92/12140). Boehringer Ingelheim disclosed a series of trifluoromethyl- and α,α-difluoromethyl-β-ketoesterpeptide derivatives as elastase inhibitors (EP 0 369 391 A2).

The present invention concerns dipeptides which contain an electrophilic derivative of an α-amino acid at P₁ conjugated with an N,N-disubstituted α-amino acid at P₂. The electrophilic functional groups used to derivatize the P₁ amino acid analog are: boronic acids and their esters, α-mono- and α-perhaloketones, vicinal di- and tricarbonyl compounds, and α,α-dihalo-g-ketoesters. The N,N-disubstituted α-amino acids are derivatives of an amino acid other than proline where the α-amino group is alkylated and acylated or diacylated to give alicyclic or cyclic substituents. As a result these compounds are found to have the advantage of an improved toxicological profile as well as the selectivity and inhibition activity for thrombin required for a useful therapeutic agent.

Synthesis

The compounds of Formula (I) can be prepared using the reactions and techniques described below, in addition to synthetic procedures described in Applicant's Assignee's commonly assigned patent applications U.S. Ser. No. 08/010,731 (filed Jan. 29, 1993), U.S. Ser. No. 08/036,378 (filed Mar. 24, 1993), and U.S. Ser. No. 08/052,835 (filed Apr. 27, 1993), all of which are hereby incorporated by reference. The reactions are performed in a solvent appropriate to the reagents and materials employed and suitable for the transformations being effected. It will be understood by those skilled in the art of organic synthesis that the functionality present on the molecule should be consistent with the transformations proposed. This will sometimes require a judgment to modify the order of the synthetic steps or to select one particular process scheme over another in order to obtain a desired compound of the invention. It will also be recognized that another major consideration in the planning of any synthetic route in this field is the judicious choice of the protecting group used for protection of the reactive functional groups present in the compounds described in this invention. An authoritative account describing the many alternatives to the trained practitioner is Greene and Wuts, Protective Groups In Organic Synthesis, Wiley and Sons (1991). ##STR13##

The preparation of the required N,N-disubstituted amino acid subunit can be accomplished by the sequence outlined in Scheme 1. A variety of methods for the asymmetric synthesis of the amino acids required for the amino acid ester substrate (II) is reviewed by Morrison and Mosher (Asymmetric Organic Reactions, American Chemical Society, 297-334 (1976) and references there in). The appropriate ester (II), where M is the ester residue, can be conjugated to give the N-substituted intermediate (III) by N-monoalkylation with an alkyl halide related to R¹¹. Typical conditions for N-monoalkylation include the admixture of an excess of (II), the required alkyl bromide or iodide and a base in an anhydrous polar aprotic solvent, such as acetone, acetonitrile, N,N-dimethylformamide or methyl sulfoxide. The option exists for stirring this mixture at room temperature or heating at temperatures up to the reflux point of the selected solvent. The base added is chosen so that it will not interfere with the ester functionality of (II); among those recommended are non-nucleophilic bases such as sodium hydride or potassium carbonate. Another general route for the preparation of compounds of this type is the reductive amination of (II) with a selected aldehyde related to R¹¹. In this procedure, a mixture of (II) and the aldehyde are heated in an anhydrous non polar solvent, such as benzene, toluene or xylene, with continuous removal of evolved water by drying agents or azeotropic distillation. This process causes condensation of the aldehyde with amine (II). The condensation product is reduced to monoalkylated (III) by treatment with a selective hydride reducing agent such as sodium cyanoborohydride or sodium borohydride, according to the method of Getson et. al., J. Heterocycl. Chem. 1, 300 (1964), or by catalytic hydrogenation with platinum, palladium, nickel or Raney nickel in an alcohol solvent like propanol, ethanol or methanol, according to the method of Hudlicky, Reductions In Organic Synthesis, John Wiley and Sons, pp. 134 (1984).

While a number of coupling or acylation methods can be contemplated for the preparation of the disubstituted derivative (IV) from (III), (see Bodanszky and Bodanszky, The Practice of Peptide Synthesis, Springer-Verlag, p. 87-150 (1984)), three methods are preferred. In the first, a solution of (III) in an anhydrous non polar solvent, such as tetrahydrofuran or dichloromethane, at -78° C. or higher is treated sequentially with a selected acid chloride related to R³ followed by a trialkylamine base. This mixture is allowed to warm to ambient temperature over several hours if required. The second method is the mixed anhydride procedure of Anderson et al. reported in J. Am. Chem. Soc. 89, 5012 (1967). In this procedure the alkyl mixed anhydride is generated by dissolving a selected carboxylic acid related to R³ in non-polar anhydrous solvent, such as tetrahydrofuran or dichloromethane, and adding one equivalent of a trialkylamine base. The solution is stirred at -78° C. or higher and one equivalent of an alkylchloroformate is added. After formation of the mixed anhydride is complete, a solution of one equivalent each of intermediate (III) and a trialkylamine base is added dropwise. The mixture is stirred with or without cooling until the reaction is complete. The third method preferred for amide formation is the hydroxybenzotriazole/dialkylcarbodiimide method of Koing and Geiger in Chem. Ber. 103, 788 (1970). Thus, to (III) and a selected carboxylic acid related to R³, dissolved in an aprotic solvent like N,N-dimethylformamide, dichloromethane or tetrahydrofuran, at -78° C. or higher, is added dialkylcarbodiimide, hydroxybenzotriazole and a trialkylamine base. If necessary, the stirred solution is allowed to thaw to ambient temperature over several hours.

An alternative preparation of N,N-disubstituted amino acids uses α-halo- or α-sulfonate acylesters such as (V) of Scheme 2. Compound (V) can be treated with a primary amine related to R¹¹ in the presence of a variety of bases like potassium carbonate, triethyl amine or sodium hydride and in solvents such as ethyl ether, acetone or dimethylformamide at temperatures ranging from -78° C. to the reflux point of the solvent selected. From this reaction can be isolated the N-alkyl aminoacid ester (III) of Scheme 1; the N-alkyl-N-acylamino acid ester (IV) can be prepared from compound (III) by any of the methods outlined in Scheme 1 and the related discussion hereafter.

The preparation of intermediates which will lead to compounds where R³ and R¹¹ may be taken together to form a cyclic amide or phthalimide is described in Scheme 2. N,N-Disubstituted α-amino acid subunits (VI) which lead to compounds of this type are best derived by reaction of an appropriate α-haloester (V), where J=Cl, Br, I. ##STR14## with the alkali metal salt of an amide or phthalimide related to the desired cyclized combination of R³ and R¹¹ in a polar aprotic solvent according to the method of Daly et. al.in J. Med. Chem. 33, 2818 (1990); Neuberger and Scott, J. Chem. Soc. p 1820 (1954). In a typical preparation the alkali metal salt of the required cyclic amide or phthalimide is generated by adding one equivalent of a strong non-nucleophilic base such as sodium or potassium hydride, a lithium dialkylamine, or lithium trimethyl- or lithium triphenylmethane to a solution of the amide or phthalimide in an anhydrous inert solvent, such as tetrahydrofuran or 1,2-dimethoxyetharle, at -78° C. or higher. When the salt formation is complete, the solvent is removed by distillation and replaced by the appropriate polar aprotic solvent such as acetonitrile, N,N-dimethylformamide or methylsulfoxide. The appropriate α-chloro- or α-bromoester is introduced and the mixture stirred at room temperature or with heating until the haloester is consumed.

It will be recognized by those skilled in the art of organic synthesis that the acid derivatives of the N,N-disubstituted α-amino acid esters (IV) and (VI) are the required precursors for the preparation of the thrombin inhibitors disclosed in this invention. It is recommended that compounds (IV) and (VI) be prepared as either the benzyl, methyl or t-butyl esters because of the ease with which esters of these types may be converted to their corresponding acids. In the case of a benzyl ester (e.g. (IV) or (VI), where M=--CH₂ C₆ H₅), hydrogenolysis of an alcohol solution of the compound may be effected under an atmosphere of hydrogen gas in the presence of platinum or palladium on carbon catalyst according to the reported by Hartney and Simonoff, Org. React. VII, 263 (1953); with a methyl ester (IV) or (VI), where M=--CH₃, treatment of an ethanol solution of the compound with an aqueous base, such as one equivalent of sodium hydroxide solution, will give the desired acid. The t-butyl ester (IV) or (VI), where M=--C(CH₃)₃, is readily cleaved by acid under anhydrous conditions; for example trifluoroacetic acid in dichloromethane solution removes the t-butyl ester of derivatives of (IV) at ambient temperature as reported by Bryan et. al., J. Am. Chem. Soc. 99, 2353 (1977). A number of alternative esters and procedures are detailed in Greene and Wuts (1991).

Scheme 3 illustrates the coupling of the acid derivatives of (IV) or (VI) with boropeptide synthons (VII) or (VIII) to give intermediates (IX) or (X). ##STR15## The preparation of synthons (VII) and (VIII) has been described by Kettner and Shenvi (EP 293 881 A2). It will be recognized by those skilled in the art of organic synthesis that the methodology described by Kettner and Shenvi can be applied to make homologous boropeptide synthons related to (VII) and (VIII). These homologues may be used in the appropriate processes described herein to prepare the corresponding thrombin inhibitors. The coupling of the carboxylic acid derivative of (IV) or (VI) to boropeptide synthon (VII) or (VIII) has been described previously by Kettner et al. in J. Biol. Chem. 265 ,18289 (1990) and, in general, the standard amino acid coupling protocols detailed by Bodanszky and Bodanszky (1984) are effective for making the compounds of this invention. Preferred methods are the mixed anhydride procedure of Anderson et al. (1967) and the hydroxybenzotriazole/dialkylcarbodiimide method of Koing and Geiger (1970). In the mixed anhydride procedure, the anhydride is generated by dissolving a carboxylic acid related to (IV) or (VI) in a non polar anhydrous solvent, such as tetrahydrofuran or dichloromethane, and adding one equivalent of a trialkylamine base. The solution is stirred at -78° and up to 0° C. , then one equivalent of an alkylchloroformate is added. After formation of the mixed anhydride is complete, a solution of boropeptide synthon (VII) or (VIII) and a trialkylamine base is added. The mixture is stirred for one hour with cooling followed by several hours at ambient temperature. By the hydroxybenzotriazole/dialkylcarbodiimide method, (VII) or (VIII) and the acids of (IV) or (VI) are dissolved in an aprotic solvent, such as N,N-dimethylformamide, dichloromethane or tetrahydrofuran, at -78° or higher. To this solution one equivalent each of dialkylcarbodiimide, hydroxybenzotriazole and a trialkylamine base are added. If necessary, the solution is allowed to stir and thaw to ambient temperature over several hours.

A process for the preparation of the boropeptide thrombin inhibitors of this invention from intermediates (IX) and (X) is disclosed in Scheme 4. Compound (IX) serves as a starting point for isothiouronium thrombin inhibitors (XI) and (XII). The boronic ester (XI) is prepared by stirring a solution of (IX) and thiourea in an inert polar solvent, such as an alcohol or N,N-dimethylformamide, at temperatures ranging from ambient to the reflux temperature of the selected solvent. It is understood that a boronic acid ester like compound (XI) is an effective thrombin inhibitor, however, it may be transformed to the corresponding free boronic acid (XII) without a loss of biological activity. Compound (XII) is derived from the boron ester (XI) by transesterification under equilibrium conditions. ##STR16## Thus stirring ester (XI) with an excess of an alkyl- or aryl boric acid in a biphasic mixture of neutral or acidic water and an immiscible solvent, such as ethyl ether or toluene, gives (XII) after several hours at ambient temperature. The conditions generally preferred use 5 to equivalents of phenylboric acid in ethyl ether/water at 10 neutral pH. Thrombin inhibitors (XIII) to (XVI) are obtained by reduction of an azide intermediate prepared from (IX) or (X). The azide intermediate is prepared by heating either (IX) or (X) with an inorganic azide, such as sodium or potassium azide, in an anhydrous polar aprotic solvent, such as acetone, dimethylformamide or methyl sulfoxide at temperatures ranging from ambient to 130° C. Alternatively, phase transfer conditions may be employed to prepare the azide intermediate from (IX) or (X). For example, a tetraalkylammonium azide in a non-polar aprotic solvent, such as tetrahydrofuran or toluene, or a crown ether and inorganic azide in biphasic mixtures of water and an immiscible solvent, such as benzene, toluene or xylene, can be stirred at room temperature or heated up to the reflux point of the selected solvent. The primary amines (XIII) and (XIV) are most conveniently obtained from the catalytic hydrogenation of the azide in an inert solvent, such as an alcohol, ethyl acetate or tetrahydrofuran with a transition metal catalyst such as platinum or palladium on carbon under an atmosphere of hydrogen gas. A variety of alternative methods are also useful and can be found in the monograph by Hudlicky (1984, pp. 76). The acid salt of the resulting amines (XIII) and (XIV) may be formed by the addition of one equivalent of the desired acid to the hydrogenation mixture. Phenylboric acid mediated hydrolysis of esters (XIII) and (XIV) gives the free boronic acid thrombin inhibitors (XV) and (XVI), compounds of formula (I) of the invention.

Compounds containing a primary guanidine or N-alkyl guanidine functionality may be prepared by the alternative process outlined in Scheme 4. As illustrated with primary amine (XIII), the transformation to (XVII) is effected with a guanidinylation agent, such as an S-alkyl thiourea, aminoiminomethane sulfonic acid reported by Miller and Bischoff Synthesis 9, 777 (1986), cyanamide reported by Kettner et al. (1990) or- their N-alkyl derivatives. This mixture is stirred at room temperature or higher with a base, such as potassium carbonate, triethylamine or N,N-dimethylaminopyridine in an inert solvent like water, alcohol, N,N-dimethylformamide or acetone. The guanidine boronic acid esters (XVII) can be deesterified to give the corresponding boronic acid (XVIII) by the phenylboric acid procedure described above.

According to Scheme 5, the bromide (X) is converted to the corresponding alkylnitrile (XIX) upon exposure to the cyanide anion under a variety of conditions. ##STR17## Effective methods include the use of potassium or sodium cyanides in polar aprotic solvents, such as N,N-dimethylformamide, methylsulfoxide, acetone or ethylmethyl ketone, at temperatures ranging from ambient up to the reflux point of the selected solvent. More useful, however, are conditions employing phase transfer agents such as tetrabutylammonium cyanide in a nonpolar aprotic solvent such as tetrahydrofuran or toluene, or a biphasic mixture of a crown ether and an inorganic cyanide in water with an immiscible solvent like benzene, toluene or xylene. These mixtures can be stirred at ambient temperature or heated up to the reflux temperature of the selected solvent. An amidine like (XX) is prepared by first treating nitrile (XIX) with a saturated solution of a mineral acid such as hydrogen chloride in an alcohol solvent at room temperature or lower. The intermediate O-alkylimidate can be exposed to ammonia, or a primary or secondary amine under anhydrous conditions with or without an inert solvent. As illustrated in Scheme 5, compound (XX) is produced by treating the O-alkylimidate formed from (XIX) with neat anhydrous ammonia at reflux. The free boronic acid (XXI) is obtained by transesterification of (XX) with phenylboric acid in a mixture of water and diethyl ether.

The formamidine substituted boronic acid (XXIII) is prepared from alkylamine (XV) as shown in Scheme 6. Compounds of (XV) can be stirred with an O-alkyl or O-aryl formimidate from 0° C. or up to the reflux temperature of an inert anhydrous solvent such as tetrahydrofuran or N,N-dimethylformamide to give formamidine (XXII). Free boronic acid (XXIII) is produced from (XXII) by the phenylboric acid transesterification protocol. ##STR18##

As shown in Scheme 7, the N-cyanoguanidine substituted boronic acid (XXVI), can be prepared by the reaction of (XV) with an N-cyanoisourylation agent such as S,S-dimethyl N-cyanoiminodithiocarbonate or O,O-diphenyl N-cyanodiimino-carbonate. In this general process, compounds of Formula (XV) are combined with a selected iminocarbonate in an inert, anhydrous solvent like tetrahydrofuran or N,N-dimethylformamide. The mixture is stirred at 0° C. or up to the reflux temperature of the chosen solvent until there is obtained an N-cyano-S-isourea or N-cyano-O-isourea of the Formula (XXIV) similar to that reported by Barpill et al., J. Heterocyclic Chem. 25, 1698 (1988). This intermediate is treated with an amine such as ##STR19## ammonia, or more generally, an alkylamine or an arylamine with or without an inert solvent like water, tetrahydrofuran or an alcohol at temperatures ranging from 0° C. to reflux to give the aminolysis product (XXV). Treatment of (XXV) as described above with phenylboric acid can provide (XXVI).

The N-hydroxyguanidino inhibitors, as shown in Scheme 8, are prepared by treating amine (XV) with cyanogen bromide or cyanogen chloride followed by hydroxylamine in an inert solvent to yield (XXVII) according to Nakahara et. al., Tetrahedron 33, 1591 (1977); and Belzecki et al., J. Chem. Soc. Chem. Commun. p. 806 (1970). Transesterification of (XXVII) by the phenylboric acid method can provide (XXVIII). ##STR20##

A general preparation for the new aromatic boronic acids is illustrated in Scheme 9. Functionalized benzylic anions containing either a halo- or cyano-substituent are obtained with a variety of metalation agents, such as activated zinc metal/CuCN•2LiCl based on the report of Berk et al. Organometallics 9, 3053 (1990); or use of lithium metal according to Michel et al., J. Organometallic Chem. 204, 1 (1981); or lithium naphthalenide in the presence of zinc chloride based on the report of Zhu et al., J. Org. Chem. 56, 1445 (1991) in an inert solvent like tetrahydrofuran or 1,2-dimethoxyethane at temperatures of -78° C. or higher. Dichloromethyl boronic acid pinanediol, prepared by the method described by Tsai et al. in Organometailics 2, 1543 (1983), is allowed to react with the transmetallated anion in the selected solvent to give (XXIX). The a-aminoboronic acid, (XXX), can be obtained by treating (XXIX) with the sodium or lithium salt of hexamethyldisilizane in a polar aprotic solvent like acetone, N,N-dimethylformamide or methyl sulfoxide with heating at temperature up to the reflux point of the selected solvent, if necessary The trimethylsilyl protecting groups are removed by treatment with ##STR21## anhydrous acid such as gaseous hydrogen chloride or trifluoroacetic acid in an inert solvent like tetrahydrofuran or dichloromethane at -78° C. or higher. Compound (XXX) was coupled to the N,N-disubstituted a-amino acids (IV) or (VI), using the techniques described in Scheme 3, to give the boronic acid ester (XXXIa). Transesterification of (XXXIa) by the phenylboric acid protocol (vide infra) gives inhibitor (XXXIb). In Scheme 9, the aromatic nitrile (XXXIa) is converted to the amidine (XXXIIa) by methods described for the synthesis of aliphatic amidine (XX) in Scheme 5. Removal of the pinanediol protecting group of (XXXIIa) gives the free boronic acid derivative (XXXIIb).

As detailed in Scheme 10, compound (XXXIa) is a versatile intermediate that can be hydrogenated to yield the aminomethyl derivative (XXXIIIa) under a variety of conditions (Hudlicky, (1984), pp 173). ##STR22## Catalysts recommended for this transformation include transition metals like rhodium, Raney nickel, nickel boride, nickel, platinum or palladium; these reductions occur readily under atmospheres of hydrogen or ammonia at pressures ranging from 1 to 300 atmospheres, at room temperature or higher, and in inert solvents such as water, an alcohol, ethyl acetate or tetrahydrofuran. Furthermore, from (XXXIIIa), the formamidino- (XXXIVa), cyanoguanidino- (XXXVa), hydroxyguanidino- (XXXVIa) and guanidino- analogs (XXXVIIa) can prepared by the same procedures described for the aliphatic series in Schemes 4, 6 through 8. The boronic acid esters (XXXIIIa)-(XXXVIIa) can all be transesterified to the corresponding free boronic acid inhibitors (XXXIIIb)-(XXXVIIb) using the phenyl boronic acid method prviously described.

Aromatic boronic acid inhibitors (XLIa,b), with the guanidine functionality substituted directly on the aromatic nucleus, can be prepared from precursor (XXXVIII) according to Scheme 11. Nitration of the aromatic ring of (XXXVIII) according to the method of Olah and Kuhn, J. Amer. Chem. Soc. 84, 3684 (1962) can occur readily with agents such as acetyl nitrate, nitrosonium tetrafluoroborate (NO₂ ⁺ BF₄ ⁻) and nitrosonium hexafluorophosphate (NO₂ ⁺ PF₆ ⁻) in inert solvents like tetrahydrofuran or dichloromethane at -78° C. or higher. The products of formula (XXXIX) can be reduced to the aniline derivative (LX) by catalytic hydrogenation. The catalysts recommended for this procedure include iron, zinc, platinum oxide, rhodium--platinum oxide, palladium, Raney nickel, copper chromite, and rhenium sulfide. While reduction occurs readily under an atmosphere of hydrogen gas at pressures range from 1 to 350 atmosphere in an inert solvent like water, an alcohol or ethyl acetate, other reagents which may affect this reaction are transfer agents such as hydrazine, formic acid or triethyl formate (Hudlicky, (1984), pp 73). ##STR23## The aniline (LX) can be converted to the phenylguanidine (LXIa) by the procedure described for (XVII) in Scheme 4. The transformation of (LXIa) to the free boronic acid (LXIb) is effected as in Scheme 4.

The several types of inhibitors disclosed in this invention can be broadly classified by their electrophilic functional group A, as defined in Formula (I). The compounds described below, unlike the boron containing peptides, utilize a highly electrophilic carbon atom at A to interact with the active site serine of thrombin. The precursor for the electrophilic carbon inhibitors is the appropriately protected amino acid (LXII) of Scheme 12. ##STR24## The preparation of (LXII) can be found in the general chemical literature, one such reference being the review by Morrison and Mosher (1976). According to Scheme 12 various terminal functional groups are available from (XLII): the formamidino- (XLIII), cyanoguanidino- (XLIV), hydroxyguanidino- (XLV) and guanidino-analogs (XLVI). These compounds are prepared by the same procedures described for the boropeptide series in Schemes 4, 6-8.

The preparation of amidine derivative (XLVIII) and phenylguanidines of formula (L) from amino acids (XLVII) and (XLIX) is shown in Scheme 13. The conditions used to prepare amidines of formula (XLVIII) is discussed for (XX) of Scheme 5 while the method for formamidinylation of (XLIX) to give (L) is the same as that described to prepare (XVII) of Scheme 4. ##STR25##

As shown in Scheme 14, appropriately protected derivatives of formulae (XLII)-(L), wherein M is an alkyl or benzyl group can be coupled with N,N-disubstituted acid (IV) or (VI) (wherein M is hydrogen). The methodology to accomplish these transformations is the same as that used to prepare boropeptides (IX) and (X) of Scheme 3. The X group in compounds of formulae (XLII) through (L) and (LI) in Scheme 14, as well as in compounds illustrated in the Schemes to follow, is a protected version of the terminal functional group X, as defined by Formula (I), unless deprotection is indicated to obtain the final compound of the sequence. ##STR26## It is understood that the protecting group(s) used should compatible with the conditions of the process discussed; a good source for information on protecting group chemistry is Greene and Wuts (1991).

The preparation of the thrombin inhibitors trihalomethyl ketone (LIII) and α-ketoester (LIV) are shown in Scheme 15. The coupled ester (LI), wherein M is alkyl or benzyl can be converted to the acid (M is hydrogen) by the methodology appropriate for the particular ester functionality as described in Greene and Wuts (1984). The aldehyde (LII) can be prepared by selective reduction of the acid (LI, M is hydrogen) to the primary alcohol followed by oxidation. ##STR27## To obtain the primary alcohol, the acid can be transformed to the mixed anhydride by condensation of the trialkylammonium salt of the acid with an alkyl- or arylchloroformate in an inert non-polar solvent such as tetrahydrofuran, 1,2-dimethoxyethane or toluene at-78° C. to room temperature. The solution of the resulting mixed anhydride is filtered and reduced to the peptidyl alcohol with an excess of a borohydride reducing agent in a compatible solvent like water or an alcohol at -78° C. to room temperature according to the method of Rodriguez et. al., Tetrahedron Lett. 32, 923 (1991). The peptidyl alcohol can be oxidized to aldehyde (LII) without over oxidation by a variety of procedures, as detailed by Hudlicky in Oxidations in Organic Chemistry, American Chemical Society, p. 114 (1991); the preferred methods include Swern oxidation described by Omura and Swern, Tetrahedron 34, 1651 (1978); and the Pfitzner-Moffat oxidation described by Fearon et al.in J. Med. Chem. 30, 1617 (1987). A two step protocol reported by Edwards, Tetrahedron Lett. 33, 4279 (1992) can be used to prepare the trifluoromethyl ketones (LIII) (J is fluorine) from aldehyde (LII). In this procedure a metallated trifluoromethyl anion is generated from an excess of trifluoromethyliodide or -bromide and an active metal such as zinc, magnesium, lithium or cadmium in inert, anhydrous solvents like tetrahydrofuran or N,N-dimethylformamide at temperatures of -100° C. up to the reflux point of the solvent. Alternatively, the metalated trifluoromethyl anion may be generated by the transmetallation of trifluoromethyliodide or -bromide with an organometallic compound such as a Grignard reagent or alkyllithium compound in an inert solvent like tetrahydrofuran, hexane or ether at temperatures ranging from -78° C. up to the reflux point of the selected solvent. Aldehyde (LII) can be added to the solution of the metalated trifluoromethyl anion to form the trifluoroethanol derivative at temperatures of -100° C. or higher. To obtain the trifluoromethyl ketone (LIII) where J is fluoro, the alcohol is oxidized by the Pfitzner-Moffat or Swern procedure. Removal of the protecting group(s) on terminal group X by the appropriate method will provide the thrombin inhibitors of formulae (LIII).

Trihalomethyl analogs of (LIII), where J is fluoro can also be prepared from aldehyde (LII) by a different method. The trihalomethyl ketones are prepared by treating aldehyde (LII) with either the trimethylsilyl trihaloacetate or the potassium or sodium trihaloacetate in a polar solvent such as an alcohol, N,N-dimethylformamide or methylsulfoxide with or without a base such as a trialkyl amine, potassium carbonate or sodium hydroxide at temperatures of -78° C. or higher according to the method of Beaulieu, Tetrahedron Lett. 32, 1031 (1991); Shell Int. Res., European Patent Application EP 16504). The resulting a,a,a-trihaloethanol is oxidized and group X can be deprotected as above to give the thrombin inhibitors or formulae (LIII).

The a-ketoester thrombin inhibitors, exemplified by (LV), are prepared according to a route disclosed by Iwanowicz et. al. in Bioorgan. Med. Chem. Lett. 12, 1607 (1992). The tris(ethylthio)methyl anion is added to the peptidyl aidehyde (LII) in a solvent such as tetrahydrofuran, 1,2-dimethoxyethane or toluene at -100° C. or higher to give the alcohol (LIV). The a-hydroxyl ester is generated from (LIV) by treatment with a mixture of mercuric salts, such as mercuric chloride and mercuric oxide, in an alcohol or water. Swern or Pfitzner-Moffat oxidation of the a-hydroxyl ester followed by the deprotection of substituent X protecting group provides thrombin inhibitors of formula (LV).

Another method for the preparation of compound (LV) substitutes a 1-lithio-1-alkoxyethene or 1-magnesio-1-alkoxyethene for the tris(ethylthio)methyl anion of Scheme 15 in an addition reaction with peptidyl aldehyde (LII). There can be obtained an adduct analogus to the tris(ethylthio)hydroxyethyl compound (LIV) when excess 1-magnesio- or 1-lithio-1-alkoxyethene anion is stirred at temperatures ranging from -100° C. to ambient temperature with (LII) in anhydrous solvents such as diethyl ether or tetrhydrofuran. This alkoxyolefin product may then be transformed to (LV) by oxidative cleavage with reagents such as ozone or periodate in an inert solvent such as a halohydrocarbon, lower alkyl ketone, an alcohol or water at temperatures ranging from -100° C. to ambient temperature, followed by oxidation of the intervening α-hydroxyester and deprotection as described above.

The preparation of the a,a-dihalomethylketone thrombin inhibitors of this invention is outlined in Scheme 16. ##STR28## The a,a-dihalomethylketone (LVII), where J is fluoro can be prepared from the aldehyde (LII) by selective reaction of the aldehyde with the anion of the corresponding dihalomethane. The metalated dihalomethane anion is generated from one equivalent each of a strong hindered base, such as lithium tetramethylpiperidide or Lertbutyllithium, and the selected dihalomethane in an anhydrous, inert solvent like tetrahydrofuran or 1,2-dimethoxyethane at -100° C. or higher according to the method of Taguchi et. al. Bull. Chem. Soc. Jpn., 50, 1588 (1977). The metalated dihalomethane anion can be added to the aldehyde (LII) at -100° C. or higher. Alternatively, the dihalomethane anion is generated from a dihalomethyl(trimethyl)silane and an anhydrous fluoride ion source such as tris(diethylamino)sulfonium difluoromethyl silicate in an inert solvent like benzene, acetonitrile or tetrahydrofuran at -78° C. or higher, then (LII) can be added to give dihaloethanol (LVI) according to the method of Fujita and Hiyama, J. Am. Chem. Soc. 107, 4085 (1985). The resulting dihaloethanol can be oxidized to ketone (LVII) by the Swern or Pfitzner-Moffat procedure. Removal of the protecting group(s) on substituent X of (LVII) gives the a,a-dihalomethylketone thrombin inhibitors.

a-Halomethylketone thrombin inhibitors can be prepared by the process illustrated in Scheme 17. The acid chloride (LVIII) can be prepared from acid (LI), wherein M is hydrogen or its trialkylammonium, sodium or potassium salt with a chlorinating agent such as thionyl chloride, oxalyl chloride or dichloromethylmethyl ether in a solvent like tetrahydrofuran or dichloromethane with or without a catalytic amount of N,N-dimethylformamide at -78° C. or higher. Alternatively, the mixed anhydride of (LI) may be prepared as described for (LI) in Scheme 15. Compound (LVIII) or the mixed anhydride of (LI) can be treated with an ether solution of diazomethane and either anhydrous hydrogen fluoride or hydrogen chloride gas according to that described by McPhee and Klingsbury, Org. Synth. Coll. III, 119 (1955); or hydrogen bromide according to the method Miescher and Kaji, Helv. Chim. Acta. 24, 1471 (1941). ##STR29## Selection of the hydrogen fluoride gas will give the a-fluoromethylketone analog, (LIX) wherein J is fluoro; and hydrogen chloride gas gives the α-chloromethylketone analog (LIX) wherein J is chloro. Deprotection of X gives the corresponding thrombin inhibitors of (LIX).

The general preparative route for the a,b-diketoester, -amide and -ketone thrombin inhibitors of this invention is exemplified in Scheme 18. Compound (LVIII) or the mixed anhydride of (LI) can be reacted with a Wittig reagent such as methyl (triphenyl-phosphoranylidene)acetate in a solvent like tetrahydrofuran or acetonitrile at temperatures ranging from 0° C. to the reflux point of the solvent to give (LX). Oxidative cleavage of the phosphoranylidene (LX) with an oxidizing agent like ozone or OXONE™ in an inert solvent such as tetrahydrofuran, dichloromethane or water at temperatures of -78° C. or higher gives the vicinal tricarbonyl compound (LXI), analogous to that described by Wasserman and Vu, Tetrahedron Lett. 31, 5205 (1990). Cleavage of the protecting group can provide thrombin inhibitors of formula (LXI). ##STR30##

The preparative routes for the synthesis of the a-mono- and a,a-dihalo-b-ketoester -amide and ketone thrombin inhibitors of this invention are summarized in Scheme 19. The exemplified b-ketoester (LXII) is available from the acid derivative (LI). The acid (LI) can be treated with carbonyl diimidazole in an inert solvent such as tetrahydrofuran or dichloromethane at 0° C. or higher to form the acyl imidazole. This acyl imidazole, or the mixed anhydride of (LI), can be further reacted with lithioethylacetate in solvents such as 1,2-dimethoxyethane or tetrahydrofuran/hexane at temperatures ranging from -100° C. to ambient temperature, according to the method of Dow, J. Org. Chem. 55, 386 (1990) to give b-ketoester (LXII). ##STR31## Compound (LXII) serves as a substrate for both mono- and dihalogenation. The α-monochloro analog of (LXIII), where J is each chlorine and hydrogen, can be prepared by controlled halogenation reactions with reagents like N-chlorosuccinimide or thionyl chloride in an inert halogenated solvent and at temperatures ranging from -20° C. to the reflux point of the selected solvent according to the methods of Uhle, J. Am. Chem. Soc. 83, 1460 (1961); and DeKimpe et. al., Synthesis 2, 188 (1987). The a,a-dihalo analog (LXIV) where J is chloro is available from halogenation with molecular chlorine in a halogenated solvent at temperatures of -20° C. or higher according to the method of Bigelow and Hanslick, Org. Syn. Coll. II, 244 (1943). Reagents such as N-fluorobis[(trifluoromethyl)sulfonyl]imide are useful for the preparation of mono- and difluoro analogs (LXIII) and (LXIV) by reacting the appropriate stoichiometry of this reagent with (LXII) in a halogenated solvent at temperatures of -78° C. or higher according to the method of Resnati and DesMarteau, J. Org. Chem. 56, 4925 (1991). Deprotection of substituent X of the halogenation products (LXIII) and (LXIV) can provide the corresponding thrombin inhibitors.

Compounds of formula (LXII) also serves as a substrate for the preparation of tricarbonyl derivatives such as (LXI) (Scheme 18). Condensation of (LXII) with an aldehyde, such as benzaldehyde, gives an b-ene-a,g-dione. This ene-dione can be oxidatively cleaved with reagents like ozone or periodate to give tricarbonyl analog (LXI).

The preparation of the mono- and dihalomethylketone thrombin inhibitors is outlined in Scheme 20. The intermediates formed in the preparation of the a-mono- and a,a-dihalo-b-ketoester thrombin inhibitors of Scheme 19 can be used in these preparations. ##STR32## The decarboxylation of these halogenation products, (LXIII) and (LXIV), can be effected by saponification of the ester with mild aqueous base such as potassium carbonate or sodium hydroxide in water miscible solvents like an alcohol, tetrahydrofuran or N,N-dimethylformamide, followed by adjusting the pH to a range of 4 to 6. This mixture can be either stirred at ambient temperatures or heated at various temperatures up to the reflux point of the solvent chosen until the formation of (LVII) or (LIX) is complete and is similar to that reported in Matsuda et. al., Tetrahedron Lett. 30, 4259 (1989). Removal of protecting group(s) can provide thrombin inhibitors corresponding to (LVII) or (LIX).

Compounds of the present invention wherein the electrophilic group A is an a-hydroxy ester are prepared according to Scheme 21. The appropriate amino acid (LXVI) is reduced to the corresponding alcohol (LXVII) via NaBH4 treatment of the mixed anhydride. (LXVII) is then oxidized to the aldehyde (LXVIII) utilizing a Swern oxidation. (LXVIII) is converted to the thiocarbinol (XIX) via a lithiated orthoethylthioformate followed by conversion to the a-hydroxy methyl ester (LXX) upon treatment with mercuric salts. (LXX) is readily converted to the peptides of the invention via coupling with (IV) (M═H) to form (LXXI) under the conditions described in Scheme 3. ##STR33##

The preparation of compounds of the present invention wherein A is an a-keto ester, a-keto acid or a-keto ester hemiacetal is shown in Scheme 22. (LXXI) is converted to the a-keto ester LXXIII via a Swern Oxidation. (LXXIII) is further elaborated to hemiketal (LXXIV) by treating with methanol or to (LXXV) by treatment with hydroxide. ##STR34##

The compounds of the present invention wherein A is an alkyl carbinol (LXXVII) or an alkyl ketone (LXXVIII) are prepared according to Scheme 23. (LXVIII) is treated with an alkyl-CeCl₂ to form the alkyl carbinol (LXXVII) which is then subjected to the Swern oxidation to yield the alkyl ketone (LXXVIII). (LXXVIII) is then further elaborated to the peptide compounds of the present invention (LXXX) by following the conditions outlined in Scheme 3. ##STR35##

Compounds of the present invention wherein R³ is an optionally substituted thiophenylbenzoyl group (LXXXIII) are prepared according to Scheme 24. The desired thiophenol (LXXXII) is coupled to the bromobenzoic acid via a copper promoted coupling reaction to form (LXXXIII). (LXXXIII) is then coupled to (IV) (M═H) under the conditions outlined in Scheme 3 to form (LXXXIV) which is then coupled to (LXXXVI) under the conditions outlined in Scheme 3 to form (LXXXV). It is understood that (LXXXV) need not be in final form and that any or all of the functional groups present may be converted to their desired final form using methods known to the skilled artisan. ##STR36##

Compounds of the present invention wherein R³ is an optionally substituted benzylbenzoyl group are prepared according to Scheme 25. An optionally substituted bromophenyl compound (LXXXVII) is converted to its phenyl lithium derivative and reacted with a bromobenzaldehyde to form the optionally substituted diphenylmethyl carbinol (LXXXVIII). (LXXXVIII) is further reduced to the substituted diphenylmethane (LXXXIX) with Et₃ SiH. (LXXXIX) is converted to XC. XC is then further elaborated to XCI arid XCII by following the appropriate outline in previous schemes. ##STR37## Inhibitors which contain a substituted phenethyl group as R¹¹ are easily prepared according to Schemne 26. The appropriate phenylacetate (XCIV) is readily dialkylated with an excess of a small, unbranched alkyl halide (R¹⁸ -X) and a suitable base such as potassium tert-butoxide to form an a,a-bisalkylated ester (XCVa). Reduction of XCVa to the primary alcohol may accomplished with many hydride reducing agents, a preferred agent being lithium aluminum hydride. Oxidation of the alcohol under Swern conditions or with pyridinium chlorochromate affords the aldehyde (XCV). (XCV) is best coupled to the appropriate glycine derivative by reductive amination, a preferred procedure being reduction with sodium cyanoborohydride. The resulting amine (XCVI) is then coupled with R³ by any of several standard amide bond forming reactions familiar to those skilled in the art. A preferred method involves treating the amine with the appropriate acid chloride in the presence of a tertiary amine base, such as N-methylmorpholine or triethylamine. Saponification of the ester affords the carboxylic acid (XCVII).

The acid (XCVII) is then coupled to (LXXXVI) and elaborated to the inhibitors of the present invention by following the procedures outlined in Schemes 3, 4, and 5. ##STR38##

Inhibitors which contain a 1,w-alkanediyl substituted phenethyl group (XCVb) as R¹¹ are easily prepared according to Scheme 27. This procedure is similar to that of Scheme 26, except that a 1,w-bifunctional alkylating agent (X-R¹⁸ -X) instead of a monofunctional alkylating agent (R¹⁸ -X). In this manner, inhibitors of the present invention with the general formula (XCVIIIb) may be prepared. ##STR39##

Inhibitors in which R³ is an acylalkyl terminated by a carboxylic acid or ester (CI) are prepared by the general route described in Scheme 28. Reaction of a suitably substituted cyclic anhydride (C) with an alkoxide such as sodium benzyl oxide affords a mono-protected diacid (CI).

(CI) is then coupled to an appropriate N-alkylglycine derivative ((IV), (M═H) by any of a number of methods known to the skilled artisan. The choice of ester groups should allow for selective deprotection of the glycine carboxylate. Preferred ester groups are methyl or ethyl on the glycine carboxylate and benzyl on the acylalkyl chain, so that saponification gives the acid (CII). (CII) is then converted to the final products (CIII) following methods described in previous schemes. ##STR40##

Part A:

To hydrocinnamic acid (10.0 g, 66.7 mmol) and 4-methylmorpholine (6.74 g, 66.7 mmol) in tetrahydrofuran (THF, 200 mL) at 0° C. was added n-butylchloroformate. The reaction was maintained at 0° C. for 15 minutes, and the hydrochloride salt of sarcosine ethyl ester (10.23 g, 66.7 mmol) followed by triethylamine (Et₃ N, 16.84 g, 166.8 mmol) was added. The reaction was allowed to thaw to ambient temperature and stirred for 18 hours. After this time, the solvent was removed and the residue partitioned between aqueous hydrochloric acid (HCl, 1 N, 200 mL) and ethyl acetate (EtOAc, 200 mL). The aqueous acid phase was extracted with additional EtOAc (200 mL), the combined organic extracts were washed with HCl (1 N, 100 mL), saturated sodium bicarbonate (NaHCO₃, 100 mL) and brine (100 mL). The organic phase was dried over sodium sulfate and evaporated to give ethyl N-methyl-N-[(3-phenyl)propiorlyl]glycine (11.81 g, 71% yield). This material was used in the next step without further purification.

Part B:

To a solution of ethyl N-methyl-N-[(3-phenyl)propionyl]glycine (11.81 g, 47.4 mmol) in ethanol (300 mL) was added aqueous sodium hydroxide (NaOH, 1 N, 94.8 mL, 94.8 mmol). The reaction was stirred at ambient temperature for 18 hour, afterwhich the solvent was removed by distillation in vacuo. The residue was dissolved in HCl (1 N, 100 mL) and the solution extracted with methylene chloride (CH₂ Cl₂, 2×100 mL). The extracts were dried over sodium sulfate (Na₂ SO₄), evaporated arid the resulting solid (9.42 g) was recrystallized from EtOAc to give the title compound (7.14 g, 68% yield) as a solid (mp: 123-126° C.).

EXAMPLE 21.1.3 Pinanediol N-{N-methyl-N-[(3-phenyl)propionyl]glycyl}-1-amido-5-aminopentaneboronate, benzenesulfonic acid salt

Part A:

A mixture of Intermediate 1 (0.31 g, 1.5 mmol), pinanediol 1-amino-5-bromopentaneboronate (0.57 g, 1.85 mmol), 1-hydroxybenzotriazole (0.20 g, 1.5 mmol), 4-methylmorpholine (0.17 mL, 1.5 mmol), and 1,3-dicyclohexylcarbodiimide (DCC, 0.33 g, 1.5 mmol) were stirred in dry CH₂ Cl₂ at 0° C. for 1 hour. The reaction was thawed to ambient temperature and stirred an additional 18 hour. After this time, the reaction mixture was diluted with CH₂ Cl₂ (25 mL) and filtered. The filtrate was washed with aqueous citric acid (10%) and saturated NaHCO₃ (25 mL each), dried (Na₂ SO₄) and evaporated. The intermediate pinanediol N-{N-methyl-N-[(3-phenyl)propionyl]glycyl}-1-amido-5-bromopentaneboronate (0.75 g, 92% yield) was carried on to the next step without further purification.

Part B:

The intermediate from Part A (0.75 g, 1.4 mmol) was heated with sodium azide (NaN₃, 0.15 g, 2.3 mmol) in N,N-dimethylformamide (DMF, 10 mL) at 100° C. for 2 hours. The reaction mixture was partitioned between water (H₂ O) and EtOAc (25 mL each), and the EtOAc layer was washed with additional H₂ O (6×15 mL).

UTILITY

The compounds which are described in the present invention represent a novel class of potent, reversible inhibitors of trypsin-like enzymes. Trypsin-like enzymes are a group of proteases which hydrolyzed peptide bonds at basic residues liberating either a C-terminal arginyl or lysyl residue. Among these are enzymes of the blood coagulation and fibrinolytic system required for hemostasis. They are Factors II, X, VII, IX, XII, kallikrein, tissue plasminogen activators, urokinase-like plasminogen activator, and plasmin. Enzymes of the complement system, acrosin (required for fertilization), pancreatic trypsin are also in this group. Elevated levels of proteolysis by these proteases can result in disease states. For example, consumptive coagulopathy, a condition marked by a decrease in the blood levels of enzymes of both the coagulation system, the fibrinolytic system and accompanying protease inhibitors is often fatal. Intervention by a synthetic inhibitor would clearly be valuable. More specifically, proteolysis by thrombin is required for blood clotting. Inhibition of thrombin results in an effective inhibitor of blood clotting. The importance of an effective inhibitor of thrombin is underscored by the observation that conventional anticoagulants such as heparin (and its complex with the protein inhibitor, antithrombin III) are ineffective in blocking arterial thrombosis associated with myocardial infractions and other clotting disorders. However, a low molecular weight thrombin inhibitor, containing a different functionality, was effective in blocking arterial thrombosis (Hanson and Harker, Proc. Natl. Acad. Sci. U.S.A. 85, 3184 (1988). Therefore, we have chosen to demonstrate utility of compounds in the inhibition of thrombin, both as in buffered solutions and in plasma. Specifically, the compounds have utility as drugs for the treatment of diseases arising from elevated thrombin activity such as myocardial infarction, and as reagents used as anticoagulants in the processing of blood to plasma for diagnostic and other commercial purposes.

Compounds of the present invention are expected to be effective in the control of aberrant proteolysis and a number of accompanying disease states such as inflammation, pancretitis, and heritary angioedema.

The effectiveness of compounds of the present invention as inhibitors of blood coagulation proteases was determined using purified human proteases and synthetic substrates following procedures similar to those described in Kettner et al. (1990).

For these assays, the rate of enzymatic (thrombin, Factor Xa, and Factor VIIa) hydrolysis of chromogenic substrates (S2238 (H-D-Phe-Pip-Arg-pNA), S2222, and S2288, respectively; Kabi Pharmacia, Franklin, Ohio) was measured both in the absence and presence of compounds of the present invention. Hydrolysis of the substrate resulted in the release of pNA, which was monitored spectrophotometrically by measuring the increase in absorbance at 405 nM. A decrease in the rate of absorbance change at 405 nm in the presence of inhibitor is indicative of enzyme inhibition. The results of this assay are expressed as inhibitory constant, K_(i).

Thrombin and Xa determinations were made in 0.10 M sodium phosphate buffer, pH 7.5, containing 0.20 M NaCl, and 0.5% PEG 8000. VIIa determinations were made in 0.05 M tris buffer, pH 7.6, containing 0.10 M NaCl, 4 mM CaCl₂, and 0.1% bovine serum albumin. The Michaelis constant, K_(m), for substrate hydrolysis was determined at 25° C. using the method of Lineweaver and Burk.

Values of K_(i) were determined by allowing 0.2-0.5 nM human thrombin or human factor Xa (Enzyme Research Laboratories, South Bend, Ind.), or 50 nM human factor VIIa (BiosPacific, Emeryville, Calif.) react with the substrate (0.20 mM-1 mM) in the presence of inhibitor. Reactions were allowed to go for 30 minutes and the velocities (rate of absorbance change vs time) were measured in the time frame of 25-30 minutes. The following relationship was used to calculate K_(i) values. ##EQU1## where: v_(o) is the velocity of the control in the absence of inhibitor;

v_(s) is the velocity in the presence of inhibitor;

I is the concentration of inhibitor;

K_(i) is the dissociation constant of the enzyme: inhibitor complex;

S is the concentration of substrate;

K_(m) is the Michaelis constant.

Using the methodology described above, representative compounds of this invention were evaluated and found to exhibit a K_(i) of less 500 μM thereby confirming the utility of compounds of the invention as effective inhibitors of human blood coagulation proteases. The results of these assays are summarized in Table 80, where +++ indicates a K_(i) <500 nM; ++ indicates a K_(i) <50,000 nM; and + indicates a K_(i) 500,000<nM; - indicates inactive.
